Description Petr Horáček 2020-05-04 13:42:13 UTC 
Description of problem:
In order to be able to configure MAC on OVS interfaces via NetworkManager, version 1.22 is needed: https://bugzilla.redhat.com/show_bug.cgi?id=1763734. We need to perform such a configuration on RHCOS 4.4, while it only has NetworkManager 1.20.


Version-Release number of selected component (if applicable):
RHCOS 4.4
NetworkManager 1.20


How reproducible:
Always


Steps to Reproduce:
1. nmcli conn add type ovs-bridge conn.interface br10 802-3-ethernet.cloned-mac-address 00:11:22:33:44:55
2. nmcli conn add type ovs-port conn.interface port10 master br10
3. nmcli conn add type ovs-interface slave-type ovs-port conn.interface iface10 master port10 ipv4.method manual ipv4.address 192.0.2.1/24
4. nmcli conn modify ovs-slave-iface10 802-3-ethernet.cloned-mac-address ae:7a:1e:41:f1:45
5. ip link show iface10


Actual results:
Shows MAC address different from the one requested (ae:7a:1e:41:f1:45)

Expected results:
OVS interface is created with the set MAC.


Additional info:
This issue should be resolved by bumping of the NetworkManager version to 1.22.
Comment 1 Micah Abbott 2020-05-04 17:41:39 UTC 
According to Errata Tool, NM 1.22 was included as part of RHEl 8.2 - https://access.redhat.com/errata/RHBA-2020:1847

All versions of RHCOS will be using the RHEL 8.2 content in the near future.  I would expect RHCOS 4.4 to get the 8.2 content as part of the first 4.4 z-stream release.
Comment 5 Jeff Ligon 2020-05-27 17:37:24 UTC 
updating summary to point at the correct release
Comment 6 Micah Abbott 2020-05-27 19:14:24 UTC 
The NM 1.22 build was tagged into the RHAOS 4.5 puddle while we test the remainder of the RHEL 8.2 content in RHCOS 4.5.

NM 1.22 was first included in RHCOS 45.81.202005212229-0; which shows up in the OCP 4.5 nightly:  registry.svc.ci.openshift.org/ocp/release:4.5.0-0.nightly-2020-05-22-011031

```
$  oc image info --output json $(oc adm release info -a ~/openshift-cluster-installs/all-the-pull-secrets.json --image-for=machine-os-content registry.svc.ci.openshift.org/ocp/release:4.5.0-0.nightly-2020-05-22-011031) | jq .config.config.Labels.version
"45.81.202005212229-0"
```

Going to set this as MODIFIED so that the bots can pull it in accordingly.
Comment 9 Benjamin Gilbert 2020-06-18 02:31:30 UTC 
Reproducer needs one other step:
0. systemctl start openvswitch

Verified correct MAC address on RHCOS 45.81.202006172129-0, which has NetworkManager-1.22.8-4.el8.x86_64.
